In fact, the title hero (whose alter-ego was Waku-san, played by Toshio Mimura) bore a strong resemblance to Super Giant (known as "Starman" in the U.S.).

The pair of Planet Prince theatrical featurettes, adapted from the Senkosha TV series, were produced by Toei Studios and filmed in black and white ToeiScope format.

[1] Toei produced two theatrical movies in 1959 that featured the Planet Prince character, but wearing a completely different, more streamlined costume (and goggled helmet) than the one worn in the tv series.

The two-part movie version (produced by Toei) is very different, as Prince of Space wears a more streamlined costume, cape, and helmet with goggles.

He (along with his henchmen) wears a large prosthetic nose and cowl that give him a decidedly chicken-like appearance, something that was constantly mocked when the film was featured on Mystery Science Theater 3000.
